Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9K31/A1M - Bosch Rexroth R901094067

Weir and lock drives keep their pilot stage on a separate circuit so it holds through heavy load changes. The 4WRZE10W8-50-7X/6EG24N9K31/A1M therefore takes pilot oil supply and return from outside, regulates 50 l/min nominal flow through spool symbol W8 and follows an analog ±10 V command value.

Benefits

• External pilot oil supply and external return, independent of the working pressure.
• Spool symbol W8, 50 l/min nominal flow, maximum flow 170 l/min.
• Version without pressure reducing valve, concealed auxiliary actuation fitted.
• Operating pressure up to 315 bar, four ports to ISO 4401-05-05-0-05.
• Analog ±10 V command value, 24 VDC supply, weight 8.02 kg.

Applications

Hydraulic steel structures, lock gates and flap weirs work with slow motion under changing load. A separate pilot supply keeps the pilot pressure alive even when the main circuit is unloaded. The size 10 subplate mounting follows ISO 4401-05-05-0-05.
